Taphole filling sand


During the electric furnace smelting, the filler in the contact part with the molten steel produces a sintered layer, which prevents the molten steel from penetrating down. The unsintered filler under the sintered layer can flow out smoothly when the steel is opened to the pallet, and with the help of the pressure of the molten steel, the sintered layer is broken to achieve the purpose of automatic pouring. The tapping filler produced by our company has the characteristics of no floating, high self-opening rate, simple operation, safe use and no pollution of molten steel.
